Dear All, I have a gas hob fitted (above an electric oven) that is currently connected using a bayonet cooker hose. However, I’ve been told by a plumber that came to do a safety check on the hob/boiler that it should be connected using a rigid pipe. I understand this to be the case unless the manufacturer’s instructions state otherwise. The hob is an Indesit P 640 A GB and the instructions say: “<u>GAS CONNECTION TO FLEXIBLE STEEL PIPE</u>: The gas feed connector to the appliance is a threaded, male 1/2" connector for round gas pipe. Only use pipes, tubes and gaskets that comply with current safety codes. The maximum length of the flexible pipes must not exceed 2000 mm. Once the connection has been made, ensure that the flexible metal tube does not touch any moving parts and is not crushed.” Does this mean that a flexible pipe could be used? My plumber seems very reliable and has seen the job and manufacturers instructions so is no doubt correct. He says that the instructions are probably referring to copper pipe which can be reasonably flexible rather than a bayonet cooker hose. I've already asked him to come tomorrow to fit the rigid pipe as its better to be safe than sorry, but I just thought I’d ask out of interest more than anything else. Thanks.
